Modular implant with stabilization

Abstract

A modular optical implant, which may comprise a base ring and an optic with features that enable assembly, alignment, and stabilization of adjunct optics. The optic may have features that interface with other optics and improve optical outcomes through rigid alignment of adjunct optics, mitigation of anterior capsule opacification, in vivo identification of optical features while implanting the lens, and reduction of refractive error. More generally, some embodiments may be an optical implant, which may comprise a posterior optic surface, an anterior optic surface, an optic edge between the posterior optic surface and the anterior optic surface, a locking tab coupled to the posterior optic surface, and an optic stabilizer coupled to the anterior optic surface.
